Breaking the Insect Population Cycle in Vegetables with Dual Modes of Action

Southeastern vegetable growers are fighting a tough battle against damaging pests like whiteflies, thrips and aphids.

Valent U.S.A. is excited to announce that Senstar™ Insecticide is now available to control these tough insect pests in brassica, leafy, fruiting and bulb vegetable production. Senstar works by combining two effective modes of action, including a first-in-class juvenile hormone analogue to exterminate eggs and a lipid biosynthesis inhibitor. By combining these two modes of action, Senstar controls all life-cycle stages to help break the insect population cycle, reduce the potential of re-infestation, lower pest counts and help achieve more marketable yields.

Here’s how it works. The dual modes of action provide both systemic activity as well as translaminar movement within the plant. The systemic activity allows for quick xylem and phloem movement to control pests colonizing new vegetative growth as well as existing foliage. The translaminar movement penetrates leaf tissue to help reach pests that feed on the underside of leaves.

These pests, which are present every year, are difficult to control and an Integrated Pest Management (IPM) approach can help control these pests today and help delay insecticide resistance in the future. IPM is an approach that combines various tools and methods including chemical and biological products, natural pest enemies and cultural methods such as sanitation, crop rotation and resistant crop varieties to manage pests at an economically acceptable level.

Senstar is an excellent fit in integrated pest management (IPM) programs, helping growers continue to effectively manage key insect pests with multiple generations per year with minimum impact to naturally occurring beneficial arthropods.

By combining two different modes of action (a first in class juvenile hormone analogue and a lipid biosynthesis inhibitor), Senstar targets pests at all life stages, including eggs, delivering long-lasting control and reducing the potential of future outbreaks that can result in insect pests bouncing back and generating reduction in yield volume and quality.
